Photoelasticity images of pulsed laser ablation in water and in air were simulated by Finite Element Method. In the paper "Compare transient stress induced in in-air and in-water laser ablation using simulation method", the Von Mises stress distribution in the target is deduced from the simulated images and is compared between the two-ablation regimes. The result confirms that pulse laser ablation in the water can induced a stress about 100 times higher than that induced in ablation in the air.

The dynamic response of a concrete pavement system with load transfer dowels under the effects of moving loads is a topic of interest to many scholars. However, to fully understand the nature of the stress-strain state of the concrete slab, load transfer dowels, and the subgrade in the pavement structure, further research is needed.

The linear elastic analysis of homogeneous, isotropic cracked bodies started in the 1900s. The existence of three dimensional corner point effects in the vicinity of a corner point where a crack front intersects a free surface was investigated in the late 1970s. An approximate solution by Bažant and Estenssoro explained some features of corner point effects but there were various paradoxes and inconsistencies.

Mixed mode I/II stress intensity factors of an edge slant-cracked plate under tensile loading were assessed. A two-dimensional finite element analysis was employed using ABAQUS. Various crack lengths and angles were analyzed. The effect of the crack location at the plate edge was also examined. Crack initiation angles were calculated.

One of the specimens to investigate the mode-I fracture toughness of rock and geo-materials is semi-circular bend (SCB) specimen. In general, initial cracks in rock test specimens are produced in two shapes: straight-edge cracks and chevron notches. The ISRM suggested SCB specimen has straight shaped notch.
